It adopts special adhesive belt joint technology with independent intellectual property rights, and take special protection measures. Belt joint adopts unique design, using proprietary formulation and production technology, fine processed from special alloy materials, 60% lighter than ordinary metal belt clip, hardness, toughness, tensile strength, fatigue resistance and other technical indicators and comprehensive performance are significantly improved.
In the way of cold vulcanization on-site, special technology and special materials are adopted to solve the problems of bonding between metal and rubber, bonding between rubber and rubber, elastic coefficient of different materials and different temperature resistance. Protect belt clips from corrosion and belt from breakage by on-site treatment.
1.Spray anticorrosive paint according to process requirements.
2.Specific process: 1.Surface sandblasting derusting up to Sa2.5 level; 2. The outer surface of the shell is painted with epoxy zinc-rich primer, Epoxy micaceous iron oxide intermediate coatings and acrylic polyurethane finish coat. 3. The inner surface of the shell and the hopper are coated with epoxy zinc-rich primer.
3.The tensioning screw, rocker arm, sleeve, nut and clamp bolt are treated with corrosion protection.
4.In order to eliminate the positive tail pressure, a single channel is adopted with an interval of 8-10 m in the middle casing.
5.Optimizing of the head wheel design. It adopts high wear resistance vulcanizing head wheel and cleaning device that can alleviate the failure of automatic correction function caused by sticky materials. The driveshaft is supported by self-positioning roller bearing and the bearing seat is dust proof structure. The surface of the driving wheel of steel structure is made of vulcanized rubber with high abrasion resistance, which is processed into a special arc with automatic center adjustment function by a large CNC lathe, and then polished to enhance the friction between the rubber and the rubber belt. The end face axle hole of the head wheel is processed with 50-60 mm steel plate, which is then polished to ensure the expansion connection between the head wheel expansion sleeve and the head shaft.
6.High strength special bolt and high wear resistance rubber backing plate are used to strengthen the effect of hopper fixing and eliminate the problems of rubber belt fatigue damage at hopper fixing place and rubber coating on head wheel drum.
Through a series of optimization design measures, the belt bucket elevator special for high tower compound fertilizer effectively solves the problems existing in the ordinary belt bucket elevator.The practical application results show that the operation is stable, energy saving and consumption reduction, and the service life is long.
